You can go to Chile and NZ, and see massive areas of monoculture forestry of introduced species, and little but introduced species in most other areas too. The result is that the native species, both animal and plant, are squeezed out because of habitat loss.
Sure places like Madagascar need a lot of land remediation, as much of the land has been deforested and then become useless even for agriculture after soil damage. But I think you have to be very careful in recommending such things as universal solutions. You need to be sure the plant will not be invasive nor impede the regeneration of the natural vegetation.

plant bamboo to soils remediation is good idea. Because bamboo is a grass plant, but it growth even faster than grass. harvest bamboo shoot and poles will remove much nitrates from the soil. But please note, all shoots and poles from the cutting must be removed out of the forest.
Nitrate Reductase（NR）is the key enzyme in Nitrate Metabolism. Rise its activities will help degradation of nitrite.
Nitrate is main nitrogen sources for most plants. Nitrate convert to Ammonia by nitrate reduction, and then combine to protein with carbohydrate, forms protoplasm of plant cell and the other nitrogen components. Nitrate Reductase activity high, its net photosynthesis rate is high also. Moso bamboo can cumulate big quantity of biomass, is due to its nitrate reductase activity is high.
